I'm currently attempting to embed Rust into racket, following along with the
tutorial at
https://doc.rust-lang.org/stable/book/rust-inside-other-languages.html. For the
most part I can get it to work when using functional programming in rust. I can
call functions that return numbers/chars, however, I'm struggling to get side
effects to work. For instance, when defining the "processs" function defined in
the tutorial, I can not get the println!("Done!") (or the other print calls) to
work in racket. I tried this both in drracket and with raco. The ffi call I
used to attempt this is:
#lang racket/base
(require ffi/unsafe
ffi/unsafe/define)
(define rust-lib (ffi-lib "target/release/embed"))
(define process (get-ffi-obj "process" rust-lib (_fun -> _int)))
(process)
Am I doing this correctly? Is this an issue I should take over to Rust's
community, or are there certain steps I need to take in order for println to
work?
Thanks!
